This e-mail flap is easily spun into exactly what Hillary needs to effect her separation from Obama. Right now, she is too tightly identified with Team Obama and needs to dump all that Obama freight. That easily includes all those foreign policy disasters, including Benghazi. "Hey," Hillary can now claim, " All of it; Obama's fault!" James Carville is only too happy to help the voters thank God that Hillary is so different from that Obama!
I can see why you might think that there is some benefit from distancing herself from Obama, but she can’t win an election without Obama’s voters and his (fraud) machine. I have thought for some time that the Dem’s know that the Country is going to unravel in the next 3 years and that they don’t really want to be the Party in office when that happens. So what do you do? You allow Hillary to run (it’s her time, right ) and then you undermine her campaign enough so she loses. When the feces hits the upright occillator, they will be the Party blaming all the problems on the Repubs.
